Fine, admit it.

'Fine,' John said, closing his eyes, unable to face her. 'I admit it. I... I am enjoying this,' he said.

Louise leaned back onto his shoulder and whispered, 'that's not all, John.'

He sighed as her hand pumped faster and faster. 'God dammit... I admit all of it. That's why I asked you here, Louise. Asked you to drive, to come in, to be my girlfriend. I admit all of it. Just... don't stop...'

Louise giggled and obeyed, only increasing her pace. 'That's good to hear, you sick fuck. I can't believe you just admitted that you're really enjoying this.' His eyes snapped open, but she hadn't stopped. 'I'm your little sister, John. That's kind of fucked up.'

'You... you won't tell anyone?' John asked, hiding the fear in his voice.

'Oh, John. Don't you worry about that right now. I mean, I am never, ever going to let you forget this, but don't concern yourself with that.' She continued pumping. 'A deal's a deal. Right now, you have a choice to make. And you better be quick, too. Don't look like you can last much longer.'
